Electric lamp



FIG. 1 is a side elevational view of an electric lamp showing my new design;

FIG. 2 is a top view thereof; and,

FIG. 3 is a bottom view thereof.

The lamp is rotationally symmetric, so the front, right side, left side and rear views are equivalent. In all of the foregoing drawings, stipling is intended to illustrate shape and contour. 

The ornamental design for an electric lamp, as shown and described.
